British Airways struggles to resume service after IT failure

British Airways hopes to resume a "Near normal" service out of Gatwick airport and operate a "Majority" of scheduled flights out of Heathrow on Sunday, but has admitted there will be some further disruption after a major global IT failure forced it to cancel all flights out of London the previous day. The airline said customers who were delayed on Saturday should not travel to Gatwick or Heathrow on Sunday unless they have "Already rebooked on to another flight". Despite BA's efforts to resume a majority of services on Sunday, aviation experts have warned the disruption could continue for several days. Alex Cruz, BA's chief executive, blamed the IT failure, which affected all of the airline's check-in and operation systems, on a "Power supply issue". The GMB trade union sought to blame the disruption on the airline's decision last year to outsource several hundred IT jobs to specialists supplied by India's Tata Consultancy Services, an accusation the airline denied.
